GCAM-USA Decarbonization Pathways for GODEEEP

GCAM-USA is a version of the Global Change Analysis Model (GCAM) with state-level detail in the United States. GCAM-USA represents the dynamic behavior and interactions of five systems (energy, water, agriculture and land use, the economy, and the climate) in 32 geopolitical regions in the world including the 50 states and the District of Columbia within the U.S. Full decarbonization of the economy by 2050 (deep decarbonization) will require a combination of solutions including carbon sequestration, new fuels, long and short-term energy storage, and new, unproven technologies such as direct air capture that have not previously been included in GCAM-USA. The Grid Operations, Decarbonization, Environmental and Energy Equity Platform (GODEEEP) provides GCAM-USA 21st century deep decarbonization simulation pathways that rely on wind, solar, hydropower, and storage to meet 2035 goals and additional technology solutions to meet 2050 goals. A brief summary of the files and directories in this data package is provided below. See the README.pdf for the specifics of each pathway, and refer to the upcoming paper: Ou, Yang and Iyer, Gokul, "State-by-state energy-water-land-health impacts of the US net-zero emissions goal", 2023, under review.
